Application ine'a July 9, 1912. Serial No, 708.457.

particularly useful inconnection with macliines wherein the gripping device is en plo ved as a traveling carrier for carrying cans or similar articles while the same are being treated, such for instance as by having solder applied thereto.

The invention has for its -object to proyide a simple gripping device which shall with certainty seize and firmly hold thecan or l'ike article while it is being fed through the machine and treated and which shall automatically discharge the. said can or other article at the desired point.

My invention consists in a traveling grip-f ping device which is einbodied in a continuous chain-like construction and-has gripping jaws which are suitably gripped upon. the. article" to be heldfand in'providing automatically acting releasing devices; further, in constructing said gripping devices as aw-s which are closed by the insertion of the article to be gripped through the instrumentality of a pivoted dog which is hit by said article on'insertion and hasan arm which clamps the jaws together; further, in providing a trip for releasing the dog which is attached to a part of the chain preceding the gripping device, upon the. turning of which the trip releases the dog thereby releasing ,the jaws andejecting the' can or other device.

A desirable manner of constructing my invention and one Way in which the same -may be used, is illustrated in the 218C011);

phnfving drawings, wherein,-

invention applied thereto' ldig' 2 is a etail longitudinal sectionof one "of myimproved gripping devices illustrating the parts in gripping position ,"after l the insertion of can; Fig. 3 is a similar view illustrating the operation fof the releasing mechanism in ejecting the can; lfig. 4 is a section on the line t ofFig. 3 looking down. i

I have illustrated my invention as 'eiubodied in a traveling carrier comprising links. A B. Upon link A. the gripping devices are nounted, and upon link ll there"- leasing devices are contained. The grip ping devices comprise jaws C l) which arr illustrated as relatively movable one to the other. In the preferred construction illus. trated the aw C as a fixed jaw, and the jaw D is pivotallv supported and has a very slight movement relative to jaw C, this movement being ust about sutlicient to perniitthe easy insertion and ejectinent of a can; The said jaws are caused to he gripped by reason of a dog E which is pivotally supported relative to the jaws so as to lie across the path oi the iucoinin,' r can F. As illustrated the dog E has two legs 6 e which are mounted upon a pivot c which. passes throughthe fixed jaw C. Upon their outer end said legs are connected by an arm a pivoted thereto upon the periphery of which is a roller 6,

As the can F is inserted between the jaws C D it WilLstrike the legs c c of the dog and will force-the same rearwardly, causing the arm (3 and its roller 0* to pinch or bind the jaws tightly together, thereby firmly gripping the can. The can will he held in this gripped position during its travel through the machine, and willbe discharged by the releasing means at the desired point. The said releasing means comprises a trip orreleasing arm G which is mounted upon The or integral with the huh I) of link Bl toe g of the said trip normally lies just at the rear of the'roller c andduring the time the links are traveling in a horizontal positionythe said trip will not affect the gripping devices. Upon the arrival however at the end of the travel, the link B will he tilted or turned as illustrated in Fig. 3 whereupon the trip G will hit against the rear side of the dog, causing the same to ride forward. thereby permitting the jaws to open and releasing the can which is" ejected by-the legs '6 0 oil thedog. This is clearly illustrated in Fig. 3', where F illustrates the can which has just bcencjected. able jaw 'D is preferablymade with a chain nel 1/ upon its upper surface which extends transverselvthereof from one side to the The mov on To E. w. Brass COMPANY, or BROOKLYN,' ION or wssr VIRGINIA.

other. This channel is preferably of a contour to fit the roller 0 although not necessarily so. By reason of -said channel when the can is being ejected and the dog is thrown forward by the trip G .to its extreme forward position, the movable dog I) is permitted .to release the can F .v \Vithout the said channel this posit-ionof the dog would. cause the said can to be again gripped.

A. convenient manner of constructing the gripping device is illustrated. 'Here the link A has a pendant flange or frame a, and to this is riveted" the fixed jaw C by rivets a which are passed through some suitable part of the said jaw, as for instance through side flanges 0. These side flanges are illustrated as extending above the body of the dog C on each side and form posts through which may pass the pivot d for-the movable dog D.

The particular machine with whichI have illustrated my invention, is one designed to. apply solder to' the can seam, and is a machineof the general type illustrated in my Patent No. 1,050,956, dated January 21,1913. The gripping devices however illustrated in. said patent are omitted, and in place there of'my improved gripping devices are-sub- 'stituted. Here the chain composed of a suc- .-'cession of. links-A B which as a wholeis lettered H, is supported upon sprockets h h which are moved from a pulley I through belt 2', pulley i worlnz' i shaft i bevel gears 2' 2' shaft iand bevel gears i i. To this machine the cans as F F may be fed hand or by any suitable feeding means, as for instance the means illustrated in my said patent. The particular construction of this machine or the manner of feeding the cans thereto, do not form part of" this present invention. f

In the machine illustrated in .Fig. 1, the cans havingbeen suitably fed to the machine and gripped between the jaws C, D, are exposed to an acid bath from tank J through roller j. They are then treated by having solder applied thereto from tank K, as for instance by the roll illustrated in my said patent, and they are then brushed if desired by a. brush L. The cans are then conveyed by the carrier H to the end thereof which is the right hand end of Fig. 1, where uponthe link B will assume the position illustrated in Fig. 3, in passing around the sprocket h ,whereup0n the trip G will throw the dog E forward. Asthc dog-passes forwardits roller 0 will pass into the channel (Z upon the upper surface of dog D, permitting thejaws D to separate as the the dogeject the can -F.

Iii-Will be seen that my invention is not limited to employment with cans, as it might equally well be used with other shapes of thin metal plates, nor is it limited n ts employment to the particular mach ne'm conlegs a e of nection with which I have illustrated it.

The purpose of this is merely to show one desirable use of the invention, Therefore although I have describediwith great detail the particular construction .of the various parts of my invention, the invention is not j necessarily limited to such particular. details of construction, as thc samc may be changed and other and equivalent devices substituted,

'within the limits of the appended claims.
